PRINTING-RIBBON SHIFTER FOR WQRKMEN TIME-CLOCKS.

' Specification of Letters Patent.

Y skilled in the art to which it appertains to make and use the same,reference being had to the accompanying drawings, and to the letters ofreference marked thereon, which form a part of this specification.

This invention relates to improvements applicable to workmentime-clocks, such clocks being em loyed to record the time upon whichworiimen enter their employment and leave said employment for the day.The invention relates specifically to means I for shifting a two-coloredprinting-ribbon so that workmens time-cards may have printed thereon inappropriate color the time of entering and the time of departing eachday. For example, regular workmen may have the time of beginning andleaving the works or factory each day printed upon their cards in onecolor-for example, blue-while irregu lar workmen may have the timeprinted upon their cards in different colorfor example,

red-so .that each class of workmen may be readily distinguished by thecolor in which the time is printed upon, their respective cards.

Preceding a detail description of the invention reference is made to theaccompanying drawings, of which Figure 1 is a-front elevation of thelower ortion of a workmans timerecording clock aving our improvementsapplied thereto.

Fig. 2 is a side elevation. Fig. 3 is a detail elevation of the cardchute or holder and the printing devices. 1 Y

In a detail description of the invention similar reference charactersindicate correspondin parts. r

The c ock mechanism is omitted from the drawings, for the reason that itis not in-- have each a upon the cards the various times are illustratedin the drawings.

Proceeding immediately to a description of the features involved in thepresent improvements, A designates a crank which is instrumental inshifting the ribbon-carriage vertically in order to present thetw0colored portions of the ribbon in printing positions relative to thetime-printing wheel. This ribbon-shifting crank 1s connected to arockshaft B, suitably mounted in the frame, and extending from whichshaft are arms C C, bifurcated at their outer ends. The outer. ends ofthese arms are loosely connected in grooves to the upper ends of sleevesD, upon which ribbon-spools D are mounted. The sleeves, D rest u onstationary bars J. The upright shafts andG are surrounded at their lowerportions by springs E, having their ends inclosed,by collars E, thelower collars being fixed to said shafts, while the upper collars slidethereon and are pressed against the upper bars J. These springs thus actto prevent the ribbon-spools from unwinding too freely by exerting aconstant pressure upon the spools through the upper collars E and thebar J; The shafts G and G are firmly supported in upper and lower barsJ. The printing ribbon is divided equally throughout its length in twodiflerent or contrasting color portions I and I- For example, one halfof said ribbon throughout its length is colored red and the other halfblue. The lower ends of the shafts G and G ear-wheel Q, by -means ofwhich the said shafts are alternately turned in opposite directions towind and rewind the printing ribbon from one spool to the other. Theserewinding movements are imparted alternately from one shaft to the otherthrough gears P on shaft P, one of such gears P engaging its respectivegear Q alternately.

P is a shifting sleeve, to which is fixed one of the gears P andto whichis also fixed a ratchet P. The latter ear is operated from theimpression-leverl, which carries upon it an arm S, which engages theratchet P The lever T o crates the impressionarmM to press the tic e'tsS and the printingribbon against the type-Wheel N, the latter wheelprintin the time on, each ticket corre sponding' to t e timeappearing-en the face of the clock. (SeeFig. 3.) The impressionarm M isactuated from the lever T through laqprojection C, which extends fromthe shaft iipon-which said impression-arm M is mounted, Aspring M isconnected to this arm and' to a stationary part of the framework, sothat the tension of the spring M tends normally to throw theimpressionlever M inwardly toward the type-wheel.

Pivoted to the lever T is a trip-lever T ,whichhas a shoulder T engagingthe trip projection C when; the lever T is lowered wer leasing said tripprojection C, and permitting the im ression arm or lever to make contactwith the tickets or cards of the workmen in order to produce'the desiredtime impres-- sion thereon. v

O designates the several partsof the shifting device by means of whichthe direction of fulcrii'med at O jected between the Y O and the upperends-of both ofsaid' levers the travel of the printing-ribbon isreversed at the'limit of each feed of the'ribbon. One of these elementsconsists of a lever which is and has its lower end progearwheels P andP.

The other one of said levers is fulcrumed at are connected by across-link, the whole constituting a shifting frame, the upperends ofwhich lie in proximity to the outer-face of the printing-ribbon. U onthe printing-ribbon there are two suita le projections U (one 'only ofwhich appears) and which extend out sufficiently from he face of theribbon to engag'e'alternately the upper ends of the levers O, andwhen-engagmg said levers from opposite sides the shaft P is thrown inopposite directions by the lower end of one of said vers engagin eitherthe wheel P or the ing connections are made between the shaft P 'and thegear-wheels P on the upright shafts G and G. The wheel 13', through wtab the shaft '1? is driven, is always in en- 7 ga%ement with thedriving-lever S. v 1 is the card holder or receiver, into which eachworkman deposits. hisca and takes the necessary impression upon enteringand leaving each day.

K is an arm projecting upwardly from the rock-shaft-B and carryingon-its upper end the pointer which points to the difi'erentportions ofthe sight-indicator K, which is sta-' This sight-indicator is dividedinto two contrasting colors L and L, corresponding to the two colors I.andiI of the printingribbon. When the rock-shaft Bis operated tionary.

, from the crank A to shift the printing-ribbon to present the desiredcolor in line with the inting -wheel, the arm K, with the pointer islikewise shifted to indicate the color upon the indicator K". In thepresent instance the upper half of the indicator K is red to correspondwith the lower half I of the he result is that alternate drivinking-ribbon, which is shown Fig. 1 to be in a position to print thatcolor upon awork- 65 man s time-card.

The card-holder B is movable along its supporting-shafts B to positionsfor the incoming and outgoing workmen, as shown on the indicator B toindicate v In and Out by a pointer B.

This shifting of the card holder or receiver is obtained through theshifting-lever B which has a connection'B with the card-receiver.

While we have described certain parts of 7-5 the well-known features ofa workmans time-clock, we do not desire to claim such portions, for thereason that theycomprise no part of our invention, our inventionrelating solely to the means for shifting a two-colored 8o ribbon toprint the time in d'iflerent colors upon workmens time-cards and tothemeans for indicating to the eye the color after each shiftingoperation of the ribbon. The clock mechanism has been purposely omitted;but 8 5 it will be understood that the type-wheel N, from which the timeis printed, is rotated from a clock. This is done throu h a shaft W,which is operated from the 0100 mechanism and imparts movement to thetime-print- .gc

ing wheel N through gears (See Fig. 3.) Having described our invention,we claim- 1. A printing-ribbon shifter, com rising u right shafts,ribbon-spools carrie upon s eeves mounted upon the upper endsof said 9 5a rockshaft, two arms extending from and in the plane. of said rockshaftand engaging the upper ends of said sleeves, a crank through which therock-shaftupright shafts,

is given movement, an'indicator-arm eXtend- 100 ing from the rock-shaft,and an indicator denoting the positions of the printing-ribbon when therockhaft is actuated to elevate or lower said ribbon. I

2. A printing-ribbon shifter, comprising'1o5 tions.
